Carrie Underwood, 29, showed some leg in her strapless Abed Mahfouz couture chiffon gown with a hip-high slit teamed with silver peep-toe heels. She wore her hair in her signature over-the-shoulder curls and loaded up on mascara and nude lip gloss.

Miranda Lambert, 28, sparkled in Randi Rahm's tone-on-tone liquid gold sequin and stone gown, which she paired with matching peep-toe heels. Her hair was done in side-parted waves and her makeup looked radiant and flawless.

Taylor Swift, 22, ditched her sparkly, sequin-adorned frocks like in years past and went with a sleek white floor-length dress with cut outs at the waist and gold detail. Her wiry curls were blown out into soft waves and she loaded up on black eyeliner and false lash strips.
